5-Hexynoic acid(CAS: 53293-00-8)

5-Hexynoic acid (CAS: 53293-00-8) is a white, crystalline solid with a molecular weight of 118.14 g/mol. It has a pungent odor and is poorly soluble in water but soluble in organic solvents like ethanol and acetone. Chemically, it is prone to dehydration and spontaneous polymerization under certain conditions.

5-Hexynoic acid is usually synthesized via the hydration of propargyl alcohol using phosphoric acid as a catalyst, followed by oxidation of the resulting propargyl alcohol to hexynoic acid. The hydrogenation of hexynoic acid can also produce hexanoic acid with high selectivity and good yield.

5-Hexynoic acid (CAS: 53293-00-8) is primarily used in the pharmaceutical industry for the synthesis of certain intermediates and in the polymer industry as a monomer. It also finds applications in the production of sensors and semiconductors.

When handling 5-Hexynoic acid (CAS: 53293-00-8), it is essential to wear appropriate personal protective equipment (PPE), including gloves and safety goggles. It should be stored in a cool, dry place away from heat sources and flammable materials. In case of a spill, it should be handled according to the safety data sheet (SDS).
